On the one side was the sluggish reptilian will for ease and sleep and death, rising sometimes to active hate… — Olaf Stapledon

[S]ervants of darkness had no lasting joy in their service. In all of them the will for darkness was a perversion of the will for the light. In all but a few maniacs the satisfaction of the will for darkness was at all times countered by a revulsion which the unhappy spirit either dared not confess even to itself, or else rejected as cowardly and evil.

[T]he individual in whom the will for the light is strong and clear finds his heart inextricably bound up with the struggle of the forces of light in his native place and time. Much as he may long for the opportunity of fuller self- expression in a happier world, he knows that for him self-expression is impossible save in the world in which his mind is rooted. The individual in whom the will for the light is weak soon persuades himself that his opportunity lies elsewhere.

Exceptionally, some monotonous work involved rather long hours, but in such cases the workers were chosen from the psychological class who thrive best on monotonous occupations in which they can day-dream.
